512=-4-2q+560
Calculate 2 to the power of 2 and get 4.
512=556-2q
Add -4 and 560 to get 556.
556-2q=512
Swap sides so that all variable terms are on the left hand side.
-2q=512-556
Subtract 556 from both sides.
-2q=-44
Subtract 556 from 512 to get -44.
q=\frac{-44}{-2}
Divide both sides by -2.
q=22
Divide -44 by -2 to get 22.
